    I've tried, but something still is not working.
    Here is the code: 
    #! perl -w

use DBI;
use DBD::ODBC;

# open connection to Access database
$dbh = DBI->connect('dbi:ODBC:fred3');

my @lines = <DATA>;
my $line;
foreach $line ( @lines ) {

my $sqlstatement = q{  SELECT Table1.Name, Table1.Address, Table1.City
+, Table1.State, Table1.ZIP, Table1.Phone FROM Table1 WHERE Table1.Bus
+Type = ?};

my $sth = $dbh->prepare($sqlstatement);
foreach my $line (<DATA>) {
  chomp $line;
  $sth->execute( $line );

my $newdir= 'c:\redone';
my $extension= ".txt";
my $target = "$newdir/$line";
open( FINAL, ">$target" ) or die "Can't open $target:$!";

#output database results
while (@row=$sth->fetchrow_array) {
print FINAL "$row[0]\n$row[1]\n$row[2] $row[3] $row[4]<br>\n$row[5]\n\
+n"}
close FINAL;

} # end of fetchrow_array

} # end of loop for each of data below

      What is not working exactly? I've noted a couple of areas that may be giving trouble 
      ....
### my $newdir= 'c:\redone';
my $newdir= 'c:/redone'; 
my $extension= ".txt";
## I would be tempted to take the preceeding 2 statements out of the l
+oop

my $target = "$newdir/$line";
open( FINAL, ">$target" ) or die "Can't open $target:$!";

#output database results
### while (@row=$sth->fetchrow_array) {
while (@row=$sth->fetchrow_array()) {
...

      Could you please be a little less specific? I'm practicing for my mindreading act. Thanks.

      You write foreach my $line (<DATA>) {, but at that point, you've already read in all of <DATA>, to @lines. What's more, you've already opened a loop over @lines -- foreach $line ( @lines ) {. Finally, you only close one of these two loops.

      You need to use strict; and pay attention to what perl tells you when the code fails.
